Abstract: PURPOSE:To intercept propagation of pressure wave and to prevent occurrence of ununiformity of density by a method wherein fluid passage walls partitioning each of driving blocks are extended toward a common fluid chamber, and at least a part of the common fluid chamber is divided in accordance with each of the driving blocks. CONSTITUTION:A recording head 10 is provided for execution of recording with ink that is guided from a common fluid chamber 4 to individual fluid passages 5 partitioned with fluid passage walls 8, and is discharged with discharge energy- producing elements driven for each of driving blocks A, B, C.... Fluid passage side walls 8A that divide the driving blocks A, B, C... are made longer than other side walls S and are extending toward the common fluid chamber 4. A member numbered 9 is a rear wall of the recording head 10; in other words, the rear wall for the common fluid chamber 4. In the ink-jet recording head 10 in the above-mentioned structure, recording image signals for each one line of recording are inputted into the recording head and the driving is made for each of the blocks A, B, C... in serial order, and thereby the recording is made for each of the lines. As the side walls 8A intercept propagation of pressure wave in this case, ununiformity of density in the recording can be prevented from occurring.

Title: Drain pump controller and controlling method for air conditioner
Inventor: ITO HIROZUMI
IPC: F24F13/22
Filed: 1995-02-20
Abstract: PURPOSE: To provide a drain pump controller in which drain can be effectively discharged with a simple structure without using a water level sensor, and a drain tube can be reduced. CONSTITUTION: The memory 10 of a drain pump controller 8 stores predetermined relationship between an ambient temperature and the number of revolutions of a drain pump and stopping conditions in such a manner that the relationship is such that the higher the ambient temperature is, the higher the number of revolutions of the pump is. A CPU 11 inputs the ambient temperature from an ambient temperature detector, collates it with the relationship stored in the memory 10 and so controls a drain pump driving circuit 12 as to rotate the pump 5 at the number of revolutions of the corresponding drain pump. The fact that the condensed water generating quantity corresponds to the ambient temperature is utilized. The number of revolutions of a compressor may be input from a compressor-number-of-revolution detector 19 to be used instead of the ambient temperature.  When the malfunction of a drain system is detected, the malfunction is displayed by a display unit 13.

IPC: F23Q2/28
Filed: 1984-02-22
Abstract: PURPOSE:To contrive to improve the safety in use by a constitution wherein an ignition lever is hindered to be pressed when the gas lighter is out of use, while the ignition lever is put away from an ignition nozzle when in use. CONSTITUTION:When the gas lighter is not intended to use or is under the state that an ignition lever 11 and a guide arm 10 are housed in a lighter main body 1, the ignition lever 11 can not be pressed down because both the edge parts of a notch 1b hinders the pressing movement of a finger tip. When the gas lighter is intended to use or is under the state that the ignition lever 11 and the guide arm 10 are drawn outwards laterally and the ignition lever 11 is pressed down, the end opposite to a fork part 4a of a valve opening lever 4 is pressed down through a projecting arm 11e, resulting in raising the fork part 4a, the rising motion of which causes to pull up an ignition nozzle 3 so as to open a valve in order to jet fuel gas. Simultaneously with this, the pressing part 6a of a piezoelectric unit 6 is pressed down through a projection 11d, resulting in striking an piezoelectric element therein so as to generate high tension current and to discharge it in order to ignite fuel gas jetting from the tip of the ignition nozzle 3. In this case, because the lever 11 is away from the nozzle 3, the safety is ensured.
